I have an array whose values are all arrays of a specific format that looks like this:
Array ( [0] => Array ( [username] => John ) [1] => Array ( [username] => Joe ) [2] => Array ( [username] => Jake ) ) and I would like to have this:
Array ( [0] => John [1] => Joe [2] => Jake ) I can do this manually with a loop but is there a better way? If not, is it possible to do this for an array of objects that have a common attribute?

Using concat method The concat method will merge two or more arrays into a single array and return a new array. In the code above, we have merged three arrays into an empty array. This will result in merging multiple arrays into a new array.
To merge elements from one array to another, we must first iterate(loop) through all the array elements. In the loop, we will retrieve each element from an array and insert(using the array push() method) to another array. Now, we can call the merge() function and pass two arrays as the arguments for merging.
Given two array arr1 and arr2 and the task is to append one array to another array. Using array_merge function: This function returns a new array after merging the two arrays. $arr1 = array ( "Geeks" , "g4g" );
Since PHP 5.5.0 there is a built-in function array_column which does exactly this.

why complicate things?
foreach($array as $k=>$v) { $new[$k] = $v['username']; } If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
